Dielectric coating compositions and recording sheets made therefrom

ABSTRACT

coating compositions useful as a dielectric layer for electrostatic recording sheet material are disclosed. The compositions comprise cellulose acetate butyrate having a butyryl content of from about 47 to about 55%, an acetyl content of from about 0.5 to about 15%, a hydroxyl content of from 0 to about 1.0% and a viscosity of from about 0.2 to about 20 seconds. Preferably, the composition includes an ester prepared from gum, wood and/or tall oil rosin at an amount of up to about 70% based on the combined weight of the cellulose ester and rosin ester.
